Volume
Whether the move had participation, or just a loud voice.
Why it matters
Price tells you what happened. Volume tells you how many people meant it.
In plain language
Volume is how much of an asset changed hands in a period. A price move on heavy volume means many participants agreed enough to act. The same move on thin volume means few people were involved — it's easier to distrust.
Thin markets move dramatically on small money, which is why tiny stocks and quiet hours produce spectacular, meaningless candles.
Volume doesn't predict; it qualifies. It answers one question about any move you're staring at: was anyone actually there?
In real life
A dress marked 'sold out' matters if the boutique stocked five hundred — less if it stocked three. Scarcity theater needs a denominator.
In the market
A stock jumps 12% on a Friday afternoon on almost no volume. By Tuesday it's back — three bored traders were never a trend.
The common mistake
Reacting to price moves without asking how many people made them. Empty-room moves reverse easily.
“A price is an opinion. Volume is attendance.”
Quick self-check
Two stocks both rise 10% today — one on huge volume, one on almost none. Which move deserves more respect?

The crowded one. Broad participation means real conviction met real money. The empty one may just be noise wearing a nice number.
